Lactic Acid Blood Test Online - Check Lactate Levels guide

What is Lactic Acid, Plasma and why is it important?

Hypoperfusion is the most common cause of lactic acidosis and hyperlactacidemia may be the only marker of tissue hypoperfusion. Suspect lactic acidosis when unexplained anion gap metabolic acidosis is encountered, especially if azotemia or ketoacidosis are not present. Evaluate metabolic acidosis, regional or diffuse tissue hypoperfusion, hypoxia, shock, congestive heart failure, dehydration, complicated postoperative state, ketoacidosis or nonketotic acidosis in diabetes mellitus, patients with infections, inflammatory states, postictal state, certain myopathies, acute leukemia and other neoplasia, enzyme defects, glycogen storage disease (type I), thiamine deficiency, and hepatic failure. A spontaneous form of lactic acidosis occurs. It is a prognostic index in particular clinical settings, especially in critically ill patients in shock. A relationship to renal disease also exists. With skin rash, seizures, alopecia, ataxia, keratoconjunctivitis, and lactic acidosis in children, consider defective biotin metabolism. Phenformin, ethanol, methanol, and salicylate poisoning and ethylene glycol may cause lactic acidosis. Acetaminophen toxicity causes lactic acidosis, sometimes with hypoglycemia. Cyanide, isoniazid, and propylene glycol are among the causes of lactic acidosis. Lactic acidosis may be due to inborn errors of metabolism.

When to consider Lactic Acid, Plasma?

When to Consider a Lactic Acid Test

You might consider this test if you are experiencing symptoms or have conditions that suggest an imbalance in your body's oxygen supply or metabolic processes. Specific scenarios include:

Symptoms of metabolic acidosis, such as unexplained fatigue, nausea, vomiting, abdominal pain, or rapid, deep breathing (Kussmaul respiration).
Suspected tissue hypoperfusion, if there is a concern that your body's tissues are not receiving enough oxygen, often seen in cases of shock or severe dehydration.
Critical illness or severe infection, to monitor your body's response and assess organ function.
Known conditions affecting metabolism, such as diabetes (especially with suspected ketoacidosis), liver disease, or kidney disease.
Post-operative complications, to evaluate recovery and detect any metabolic disturbances.
Exposure to certain toxins or medications which can induce lactic acidosis.
If a healthcare provider suspects an inherited metabolic disorder, especially in children.

Who benefits from Lactic Acid, Plasma?

Who Benefits from a Lactic Acid Test?

This test is particularly beneficial for individuals who may be experiencing or are at risk for conditions that affect the body's metabolism and oxygen delivery. This includes:

Individuals in critical care settings, especially those in shock, with severe infections, or organ failure.
Patients with chronic health conditions, such as diabetes (especially with suspected ketoacidosis), liver disease, or kidney dysfunction.
Those with unexplained symptoms, such as fatigue, rapid breathing, or confusion that could indicate metabolic imbalances.
People with suspected muscle disorders, as some myopathies can affect lactate levels.
Individuals on certain medications, as some drugs can impact lactic acid metabolism.

When is the Lactic Acid, Plasma used?

Commonly Used For Diagnosis Of

Lactic Acidosis and Metabolic Acidosis
Tissue Hypoperfusion and Hypoxia
Various Forms of Shock (e.g., septic, cardiogenic)
Congestive Heart Failure
Severe Dehydration
Complications in Post-Operative Patients
Diabetic Ketoacidosis (DKA) and Nonketotic Acidosis

Glycogen Storage Diseases (e.g., Type I)
Hepatic Failure and Liver Dysfunction
Thiamine Deficiency (Beri-Beri)
Defective Biotin Metabolism (especially in children with specific symptoms)
Poisoning by certain substances (e.g., ethanol, methanol, salicylates, cyanide, acetaminophen overdose)

Important Considerations

It is important to remember that abnormal lactic acid levels can indicate a variety of underlying conditions, some of which may be serious. Always discuss your results with a healthcare provider who can interpret them in the context of your overall health, symptoms, and medical history. This test is a tool to aid diagnosis and management, not a standalone diagnostic. Factors like hemolysis of the blood sample, recent exercise, or certain medical treatments can also influence results.
